Referring to the drawing,

Fig. 1 is a condensed side view of a pipe embodying the invention upon an enlarged scale with the upper portion of the bowl and the cover structure shown in section;

Fig. 2 is an elevation from the right of Fig. 1;

Fig. 3 is a view of the cover structure removed from the pipe with the cover plate raised; and

Fig. 4 is a section on the line 44 of Fig. 3.

Like numerals refer to like parts throughout the several views.

In the embodiment of the invention shown in the drawing, the bowl III of the pipe is of cylindrical form with a slight taper toward the top thereof, the shank of the pipe being shown at Hand the bit at I2. Pipes are made with many different sizes and designs of bowls and bits, and the cover must be so proportioned as to adapt it for use with each particular size and design of pipe.

This cover mechanism consists of a cover plate I 3 resting upon the top of the bowl of the pipe. The central portion of the plate I3 is bulged upwardly at I4 and provided with draft openings.

Co-operating with the cover plate I3 is a hinge plate I5, this hinge plate being shaped so as to conform to the curvature of the outer surface of the bowl of the pipe with which the cover structure is to be used. With this construction, side tilting of the plate by reason of the curvature of the bowl and of the plate is prevented.

The cover plate I3 is connected with the hinge plate I5 by means of an ordinary hinge I6, the sockets of which are located above the plane of the edge of the cover plate I3. By using a tight hinge between the cover plate and the hinge plate, suflicient resistance is offered to the turning of the cover plate to hold this plate in the position shown in Fig. 3, when removing ashes from the pipe or charging tobacco thereinto. In other words, the cover plate may be turned about its hinged connection with the hinge plate to any extent up to 180 or more and have the cover plate remain in any position when the turning movement is arrested.

The cover plate is provided with a short tongue I! projecting beyond the top of the bowl to facilitate the opening of thecover.

While the shape of the hinge plate conforms with the exterior of the bowl adjacent the top thereof and prevents turning of the plate about an axis at right angles to the axis of the bowl, it is essential, when securing the cover upon the pipe, that this plate be held firmly against the bowl, since any looseness of the plate will permit a slight tilting action thereof, resulting in the marring of the surface finish of the bowl as a result of the scraping of the metal of the hinge plate across this surface. This will occur even though the amount of the movement of the plate be small.

Because of this necessity, I provide the hinge plate with a resilient portion which, in the form of the invention shown, consists of a spring tongue IB, the tension of which is such as to normally force thehinge plate toward the bowl as the result of the engagement of this resilient spring tongue I8 is integrally formed with the plate I5 and projects toward the hinge connection I6 between the plate and the top cover and outwardly of the bowl.

The use of a spring tongue as shown has been found to be highly desirable in securing the maximum pressure of the plate against the bowl toward the top of the former, and as also permitting the tensioning of the resilient portion or spring tongue with a gradually increasing pressure by a movement of the plate downwardly of the bowl. In this manner, the attachment of the spring plate I5 and its detachment from the bowl is a very simple operation, and is accomplished by a right line movement of the hinge plate along the bowl, thus avoiding any such tilting of the plate as might bring the edge of the plate in contact with the bowl and cause possible scratching of the surface of the latter.

In the form of the invention shown, the hinge plate is secured to the bowl by means of a headed stud I9 carried by the bowl, the head of the stud being spaced from the surface of the bowl a distance substantially equalling the thickness of the metal stock in the hinge plate I5. The use of a resilient tongue permits thin sheet metal to be used for the hinge plate, and the resiliency inherent to the tongue ensures a tight fit between the plate and the outer surface of the bowl, notwithstanding irregularities in said surface, in the spacing of the head of the stud I9 from the bowl or in the hinge plate itself.

The tongue I8 is provided with a keyhole slot 20, the enlargement of which is adjacent the end of the tongue connected with the plate I5. The tongue, adjacent the reduced portion of the slot, may or may not have a close sliding fit between the stud and the bowl. So long as the plate I5 is in close contact with the surface of thebowl, movement of the hinge plate, except in a direction parallel with the axis of the bowl or toward and from the stem, is prevented by the close fitting of the hinge plate and the bowl.

By using a resilient portion of the spring plate for securing a close fit between same and the bowl, accidental displacement of the cover is prevented, and yet the hinge plate may havea free sliding movement in relation to the stud IS in placing the cover upon or removing it from the bowl.

In mounting the cover upon the bowl, it is merely necessary to pass the enlarged portion of the keyhole opening 20 over the stud. At this point, the tongue I8 is substantially in the same plane as the rest of the hinge plate. The hinge plate I5 is then forced downwardly witha sliding movement along the surface of the bowl, and as the portion of the tongue I8 having the reduced portion of the keyhole opening passes along the bowl, the spring tongue is forced downwardly within the opening in the hinge plate. whole hinge plate toward the bowl of the pipe as a result of the tendency of the tongue to have a reflex action, and while there may be slight clearance between the tongue and, the surface of the bowl because the head of the stud I9 is spaced from the bowl a distance slightly greater than the thickness of the metal stock in the hinge plate, this is immaterial since all other portions of the plate will be spring pressed into contact with the bowl.

The spring thus tensioned will force the The spring tongue [8 has the same curvature as the hinge plate l5, while the stud has an angular shoulder presented towards the bowl of the pipe. Consequently, the portion of the head ofthe stud overhanging the tongue at opposite sides of the slot will, when applying the cover to the bowl, readily engage the head of the stud, thus permitting a fairly close fit between the head of the stud and the bowl of the pipe. The degree of pressure exerted by the tongue may be varied by changing the angle of projection of the tongue in relation to the normal plane of the hinge plate. The head of the stud est portion of the bowl only a few thousandths of an inch, possibly from .0 to .015, and the head may be rounded to avoid exposed abrupt edges.

When the cover has been attached in the manner described, a pipe with the cover thereon may be carried in the pocket and handled in the usual manner with little or no likelihood of the accidental escape of the hinge plate from the stud. The cover may be turned to open and close the bowl as desired, and this movement will have no tendency to displace the hinge plate 15. To remove the cover it is merely necessary to raise it and pull it away from the top of the bowl. This movement will cause the hinge plate to slide along the bowl without scratching same until the head of the stud is positioned within the enlarged portion of the keyhole slot 20, whereupon the hinge plate may be moved from the bowl, the stud remaining in position thereon.

The small size of the head of the stud and its 3 position in relation to the bowl will not be objectionable if it be desired to smoke the pipe without the cover thereon. In fact, studs having heads of distinctive forms may be used as a trade indicia of the origin of the pipe.

It is essential that the resilient portion of the tongue l8 of the hinge plate shall project outwardly of the bowl to get the desired spring action in fitting the hinge plate to the bowl.

The cover plate l3 and the: hinge plate are preferably made of German silver or other metal stock plated with a metal which will not readily tarnish when subjected to heat. As a matter of fact, the bowl of the pipe protects the hinge plate from the effects of the heat, and the draft downwardly of the bowl through the draft openings in the central portion M of the cover plate will protect the outer finish of said plate, although the inner surface thereof may be smutted by the smoke and ashes from within the bowl.

It is not my intention to limit the invention to the precise details of construction shown in the drawing, it being apparent that such may be varied without departing from the spirit and scope of the invention.

Having described the invention, what I claim as new and desire to have protected by Letters Patent, is:
